Go watch "Up".

It's a Pixar movie. That should be all the recommendation you need.

I've spent the past few hours looking for a flaw, and the only one I can think of was that I didn't see it with enough people in the theatre. I'm man enough to admit I'm still wibbling. If you know anything about animation at all, the cloth physics alone should leave your jaw on the floor.

tl;dr: See it.
